What experience does your company have with solar installations?

Some solar companies have been in business a long time, but the industry is growing fast. The number of contractors to choose from is increasing. Ask for references. Check with previous customers to learn if they were satisfied.

What kind of solar experience do you have?

Ask potential contractors how many systems of the type you’re considering they have installed. If you are considering both solar water heating and solar electric, you may consider a contractor who can install the systems simultaneously.

What kind of warranty and maintenance agreement do you offer?

A system warranty is essential. Energy Trust trade allies and Oregon Department of Energy tax credit-certified technicians must provide a two-year system warranty that covers any repairs resulting from defects in equipment or contractor workmanship. Some installers offer longer warranties. Make sure your contractor agreement is explicit about what issues the contractor will handle and what service to expect if something goes wrong.

What products does your company offer?

If you are looking for a particular style or brand of product, confirm that your contractor is authorized to install what you want. Some contractors offer only one brand of inverter, module or collector.
